Golf Club Head or Other Ball Striking Device Having Impact-Influencing Body Features

Abstract

A ball striking device, such as a golf club, includes a head with a face having an outer surface configured for striking a ball, a body connected to the face, and a channel located in the body. The channel is configured to influence the characteristics of the impact of a ball on the face, such as by flexing or compressing in response to the force of the impact, exerting a response or reaction force on the face, changing the motion or behavior of the face, and other manners. The head may also include a pair of channels that have a gap between them.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to and the benefit of United States Provisional Patent Application No. 61 / 228,500, filed on Jul. 24, 2009, which is incorporated herein by reference in its entirety and made part hereof.BACKGROUND[0002]Golf is enjoyed by a wide variety of players—players of different genders, and players of dramatically different ages and skill levels. Golf is somewhat unique in the sporting world in that such diverse collections of players can play together in golf outings or events, even in direct competition with one another (e.g., using handicapped scoring, different tee boxes, etc.), and still enjoy the golf outing or competition. These factors, together with increased golf programming on television (e.g., golf tournaments, golf news, golf history, and / or other golf programming) and the rise of well known golf superstars, at least in part, have increased golfs popularity in recent years, both in the United States and ...

Problems solved by technology

Despite the various technological improvements, golf remains a difficult game to play at a high level.

Off-center hits may tend to “twist” the club face when it contacts the ball, thereby sending the ball in the wrong direction, imparting undesired hook or slice spin, and / or robbing the shot of distance.

Club face / ball contact that deviates from squared contact and / or is located away from the club's desired ball contact location, even by a relatively minor amount, also can launch the golf ball in the wrong direction, often with undesired hook or slice spin, and / or can rob the shot of distance.

However, because golf clubs are typically designed to contact the ball at or around the center of the face, off-center hits may result in less energy being transferred to the ball, decreasing the distance of the shot.

Drag created by friction between the sole of the club head and the playing surface can reduce the speed of the swing and the resultant velocity and distance of the shot.

Additionally, forces between the club head and the playing surface can twist or otherwise alter the direction or orientation of the club head during the swing, which can also reduce distance, velocity, and accuracy, as well as imparting unwanted spin on the ball.
